Buying Guide
- What kind of trunk space do you have? Measure available width, height, and depth to ensure the box or pallet will fit without obstructing latches or hinges.
- Sealed versus open design: sealed boxes protect from moisture and dust, while open hold-downs are simpler but may require additional protection for the battery.
- Battery type and size: confirm your battery dimensions, terminal layout, and weight to avoid fit issues and ensure proper mounting strength.
- Material and durability: billet aluminum offers strength and rigidity, but stainless or coated variants may resist corrosion longer in harsh environments.
- Wiring and hardware: some kits exclude cables and mounting hardware. Plan to source appropriate cables, terminals, nuts, and bolts separately.
- Installation effort: check if the kit requires drilling or custom brackets. Some kits are “bolt-on” while others demand more fabrication.
- Future upgrades: consider whether you might add a second battery or relocate additional components, and whether the kit provides scalable mounting solutions.
